IMPROVED MACHINE FOR UNHAIRING HIDES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JUDSON SCIIULTZ, of Ellenvillc,"in the countyof Ulster, and State of New York, have invented a new and improved Machine for Unhairing Hides; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others 'skilled in the art to 'make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-f Figure 1 is a side view ofV my improved machine.

Figure 2 isan end view of the saine.

i Similar letters of reference indicate like parts. g

My invention has for its object to furnish an improved machine by nieans of which hides may be unhaired and leather scrubbed, scoured, or washed conveniently, thoroughly7 and rapidly; and it consists in the combination of an apron or belt, wound upon or passing around two rods or rollers, with the knife-cylinder; inthe `combination of'a pawl and ratehet-whecl and ofa ratchet-lever and rack with the ends of the belt-rollers, for

the purpose of tightening-and holding the belt and shifting its position; and iu arranging the belt or apron, knife-cylinder, and feed-rollers with eac-h other in such a manner thatfthe hides or leather may pass frein the feed-rollers beneath the knife-cylimlers in thesauic direction in which the said cylinder is revolved, but at a less velocity. l

A is the frame of the nlachine, near the middle part of which is pivotcd a cylinder, B, having knives or Scrapers C attached to. its face and extending longitudinally with it. To the rear part of the frame A are pivoted thefeed-rollers D and E, in such a position that the upper side of the lower roller D may be about upon ra level with the upper side of the knife-cylinder B. The surfaces of the rollers D and E are grooved or uted longitudinally, and the, upper one, E, is set a little in advance of thelower one, for convenience in feeding in the hides. The journals of the upper roller E revolve in bearingsin thev frame of the machiue,`the= upper parts` of which bearings are movable, and are held down to their places Vby rubber or other springs, so that the said roller may adjust` itself to Vthe varying thickness 'of the hides passing between it and the roller D.V F is an apron, the ends of which are att-ached to the rods or cylinders G and H, and which is wound upon the roller G,

so that as one part of said apron becomes worn, its position may be shifted so as to expose anothel` part to the action ofthe hides and knife-cylinder. -If desired, the ends of the apron F maybe secured to each other so. as to change it to-a belt, the position of which maybe shifted by revolving one or the other of the rollers around which it passes. The apron or belt Fniay be made of canvas, leathery'or rubber, asfm'ay be desired. The rollers or rods G and H'revolve in bearings in the frame of the machine in about the same horizontal line with the'bearings of the knifefcylinder B. To the projecting end of the journal of the roller G' is attached a ratchetwheel, I, upon the teeth of which the pawl J takes hold, to keep the said roller from revolving. To the projecting end of the roller H is attached'the end of the pawl-lever K, by means'of which the said roller is revolved to shift or .tighten the apron or belt F, and which is held in place by catching upon the teeth of the 4rack L,`

attached to lthe fraine A. The machine is driven by applying power to the projecting end of the journal of the knife-cylinder. B by means of a crank, M, pulley,ror other convenient means. To the other projecting end of` the journal ofthe said -knife-cylinder is'attached a gear-wheel, N, into the teeth of which mesh the teeth of the large gear-wheel O attached to the journal,ofthefeed-roller D, which also has a small gear-wheel, P, attached to it, meshing into the teeth of the gear-wheel R, of exactly the same size, attached to the-journal of the Vfeedroller E. By this arrangement of the gearing the two feed-rollers will be driven at the same velocity, which will be considerably slower than the velocity of the knife-cylinder B.

In using the machine, the hides or leather are fed'in between the feed-rollers D and E, and pass below the knife-cylinderB, between it and the apron or belt F, and moving at a much less velocity thanv the surface ofthe said cylinder, the unhairing, scouring, scrubbing, or washing .being done by the knives C while moving in the same direction as the hide or leather is moving, rendering it impossible for the hide or leather to wrinkle or fold under' the action ofthe knives. A

Wha-t I claim as new, and desire' to secure by Letters Patent, is@ l 1 v 1. The combination of the apron or belt E, wound upon or passing around the rollers G and H, with the knife-cylinder B, substantially as herein shown and described, andfor the purpose set forth.

sans 2 2. The combinetion ofthe ratchet I, panfl J, pztwl-leifer K, and rack L, with the journals of the apron or belt-rollers G and H, for the purpose of'holding and tightening the belt or apron F, and shifting its position, substantially as herein shown und described.

' 3. Arranging the apron or belt F, the knife-cylinder B, and'feed-rollers D :tml E with each other, substantially in the manner herein shown and described, so that the hides or leather may be fed tothe knife-cylinder B in the same direction in which the seid knife-cylinder is moving.

4. -Arranging the gearing N PR in the manner herein shown :tud described, so that the feed-rollers D and E may be driven at :t less velocity than the knife-cylinder B, as and for the purpose herein set forth.
